Terpenoid trans‐caryophyllene inhibits weed germination and induces plant water status alteration and oxidative damage in adult Arabidopsis

Plant Biology (2016)

Fabrizio Araniti Adela M. Sánchez‐Moreiras Elisa Graña Manuel J. Reigosa Maria Rosa Abenavoli

trans-Caryophyllene (TC) is a sesquiterpene commonly found as volatile component in many different aromatic plants. Although the phytotoxic effects of trans-caryophyllene on seedling growth are relatively explored, not many information is available regarding the phytotoxicity of this sesquiterpenes on weed germination and on adult plants. The phytotoxic potential of TC was assayed in vitro on weed germination and seedling growth to validate its phytotoxic potential on weed species. Moreover, it was assayed on the metabolism of Arabidopsis thaliana adult plants, through two different application ways, spraying and watering, in order to establish the primary affected organ and to deal with the unknown mobility of the compound. The results clearly indicated that TC inhibited both seed germination and root growth, as demonstrated by comparison of the ED50 values. Moreover, although trans-caryophyllene-sprayed adult Arabidopsis plants did not show any effect, trans-caryophyllene-watered plants became strongly affected. The results suggested that root uptake was a key step for the effectiveness of this natural compound and its phytotoxicity on adult plants was mainly due to the alteration of plant water status accompanied by oxidative damage.

The Role of Salicylic Acid in Plants Exposed to Heavy Metals

Molecules (2020)

Anket Sharma Gagan Preet Singh Sidhu Fabrizio Araniti Aditi Shreeya Bali Babar Shahzad

Salicylic acid (SA) is a very simple phenolic compound (a C7H6O3 compound composed of an aromatic ring, one carboxylic and a hydroxyl group) and this simplicity contrasts with its high versatility and the involvement of SA in several plant processes either in optimal conditions or in plants facing environmental cues, including heavy metal (HM) stress. Nowadays, a huge body of evidence has unveiled that SA plays a pivotal role as plant growth regulator and influences intra- and inter-plant communication attributable to its methyl ester form, methyl salicylate, which is highly volatile. Under stress, including HM stress, SA interacts with other plant hormones (e.g., auxins, abscisic acid, gibberellin) and promotes the stimulation of antioxidant compounds and enzymes thereby alerting HM-treated plants and helping in counteracting HM stress. The present literature survey reviews recent literature concerning the roles of SA in plants suffering from HM stress with the aim of providing a comprehensive picture about SA and HM, in order to orientate the direction of future research on this topic.

Genetic, metabolic and antioxidant differences among three different Calabrian populations of Cynara cardunculus subsp. cardunculus

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology (2020)

Antonella Muto Adriana Chiappetta Fabrizio Araniti Innocenzo Muzzalupo Mariangela Marrelli

Cynara cardunculus subsp. cardunculus, belonging to Asteraceae family, and widely distributed in the Mediterranean area, exhibits high nutraceutical and nutritional potential, as compared to the cultivated varieties. This work reports, for the first time, on genetic and metabolic characteristics of three natural populations of C. cardunculus present in the Pollino National Park (Calabria, Italy), referred to as wild cardoons, collected in different areas (Castrovillari, Trebisacce and Sibari). One wild and one cultivated sardinian genotypes were also analysed as comparison. Six nuSSRs markers, were used to assess population structure and diversity. The obtained results showed that all three populations genetically diverge from the cultivated one and cluster with sardinian wild populations. Moreover, PCoA and Bayesian clustering analyses evidenced that Trebisacce and Sibari populations were closer to each other compared to Castrovillari one. HPLC analysis, also revealed a metabolic profile particularly rich in phenolic acids for Sibari population which also exhibited the highest capacity to protect linoleic acid from peroxidation. To long-term, these results could be useful to preserve biodiversity and promote ecotypes with major nutraceutical proprieties.
